How much do the lengths weigh?
| 6 m lengths | 1 | 5 | 10 | 25 | 50 | 100 |
|---|---|---|---|---|---|---|
| Weight | 8.24 kg | 41.22 kg | 82.44 kg | 206.1 kg | 412.2 kg | 824.4 kg |
| Metres | 6 m | 30 m | 60 m | 150 m | 300 m | 600 m |
How much load does the 100 × 45 × 1.8 rectangular tube take?
Supported at both ends, with the load at midspan: how many kilos it takes before it bends more than 1/200 of the span (what windows and light structures usually accept) or goes past the elastic limit of 6063-T5 aluminium.
| Span | 0.5 m | 1 m | 1.5 m | 2 m |
|---|---|---|---|---|
| Upright (100 mm high) | 1,400 kg* | 700 kg* | 465 kg* | 280 kg |
| Flat (45 mm high) | 890 kg* | 320 kg | 140 kg | 80 kg |
Moment of inertia 65.93 cm⁴ upright · 18.93 cm⁴ flat; section modulus 13.19 cm³ upright · 8.42 cm³ flat. * Here the strength of the material governs, not the deflection. A guidance calculation for a straight beam with sharp corners, E = 69 GPa, without its own weight or buckling of thin walls: for a structure, the check must be done by an engineer.
